FAW J6P مغزل الصندوق الفرعي: تفكيك 14 الأجزاء المهمة لإخراج نطاق لا تشوبه شائبة

Welcome to this expert analysis of the FAW J6P مغزل الصندوق الفرعي, or auxiliary box mainshaft, for the CA10TA160M 10-speed transmission. This component is a cornerstone of the FAW Jiefang CA3250P66K2L1T1E 6×4 dump truck’s drivetrain. هذا الدليل يفكك 14 critical parts that make up the complete FAW J6P مغزل الصندوق الفرعي حَشد.

ال FAW J6P مغزل الصندوق الفرعي is the final output shaft of the entire gearbox. Its logic is to receive power from the main box (via the Sub-Box Drive Gear) and then, using its integrated Hi/Lo synchronizer, transmit that power *either* through its “قليل” gear set or in “عالي” (direct drive) to the output flange and driveshaft.

جوهر 1: ال “Spindle & Output Flange” منطق (The Core Shaft)

This group represents the “العمود الفقري” and the final “الإخراج” of the entire gearbox. إنه FAW J6P مغزل الصندوق الفرعي نفسها, and the flange that connects it to the rest of the truck.

1. عنصر: ‘Output shaft – auxiliary box’ (1701541-A7G)
هذا (شركات 5) is the ‘Output shaft – auxiliary box’, the component we refer to as the FAW J6P مغزل الصندوق الفرعي. This is a massive, single-piece shaft, precision-machined with multiple splines, steps, and bearing surfaces.

ال Dual-Path Logic is its function. Its front “tip” receives power from the main box. Its main body is splined to hold the “Hi/Lo” synchronizer assembly (شركات 2, 3, 4). Its rear section is splined to hold the ‘Output flange’ (شركات 13). This one shaft manages two different power paths (Hi and Lo).

2. ال “Output Flange” مجموعة (شركات 13, 14, 12)
This group includes: ‘Output flange’ (شركات 13), ‘Lock nut assy’ (شركات 14), and ‘Dust cover – output flange’ (شركات 12). This is the final connection point of the FAW J6P مغزل الصندوق الفرعي.

ال Connection Logic is the job of the ‘Output flange’ (شركات 13). This is a heavy-duty yoke flange. Its internal splines slide onto the external splines at the very rear of the FAW J6P مغزل الصندوق الفرعي (شركات 5). This flange is what the truck’s main driveshaft bolts to.

ال Retention Logic is the job of the ‘Lock nut assy’ (شركات 14). This is a massive, high-torque nut that threads onto the end of the FAW J6P مغزل الصندوق الفرعي. It physically “تسحب” the flange (شركات 13) and the main bearing (شركات 9) together, setting the bearing pre-load and ensuring the flange can never slide off.

ال منطق الختم is the job of the ‘Dust cover’ (شركات 12). This is a stamped metal shield, often pressed onto the flange, that works with the main output seal to protect the seal from road debris, ماء, and dirt, ضمان فترة طويلة, leak-free life for the FAW J6P مغزل الصندوق الفرعي.

جوهر 2: ال “Hi/Lo Range Synchronizer” منطق (The Shifter)

هذا هو “shifter” of the auxiliary box. This entire assembly slides on the FAW J6P مغزل الصندوق الفرعي to select either the High (direct drive) or Low (gear reduction) range.

1. ال “Synchronizer Hub” مجموعة (شركات 2, 4)
This group includes: ‘High gear synchronizer cone assy’ (شركات 2) and ‘Low gear synchronizer cone assy’ (شركات 4). هذه هي “hubs” of the synchronizer.

ال Friction Logic is their function. هؤلاء “cone” assemblies are the friction surfaces. When the driver selects “Hi” range, the ‘Sliding gear sleeve’ (شركات 3) pushes against the ‘High gear cone’ (شركات 2). This cone’s friction surface rubs against the ‘Sub-Box Drive Gear’ (from the previous breakdown), matching its speed to the speed of the FAW J6P مغزل الصندوق الفرعي. This synchronization prevents gear “grind” during a range shift.

The same action happens in reverse: when selecting “Lo,” the sleeve (شركات 3) pushes the ‘Low gear cone’ (شركات 4) against the ‘Low gear’ (شركات 7) to match its speed to the FAW J6P مغزل الصندوق الفرعي.

2. عنصر: ‘Sliding gear sleeve – auxiliary box synchronizer’ (1701561-A7G)
هذا (شركات 3) is the ‘Sliding gear sleeve’. هذا هو “shifter” نفسها. It has internal splines that lock it to the FAW J6P مغزل الصندوق الفرعي. An external groove is where the air-powered shift fork sits.

ال Locking Logic is its function. When the driver selects “Hi,” this sleeve slides forward, engaging its internal “dog teeth” with the external dog teeth on the ‘Sub-Box Drive Gear’. This creates a 1:1 “direct drive,” locking the input to the output.

When the driver selects “Lo,” this sleeve slides *backward*, disengaging from the drive gear and engaging its teeth with the ‘Low gear’ (شركات 7), locking *it* to the FAW J6P مغزل الصندوق الفرعي. This routes power through the reduction gear set.

3. عنصر: ‘Spring – auxiliary box synchronizer’ (1701551-A7G) – الكمية 3
هؤلاء (شركات 1) هي “detent” الينابيع. These three springs sit in the synchronizer hubs (شركات 2/4) and push on small “keys” (أو “الدعامات”). Their logic is to provide the “detent” أو “snap” that holds the ‘Sliding gear sleeve’ (شركات 3) in its Neutral position, preventing it from accidentally engaging.

جوهر 3: ال “Low Range Gear” منطق (The Reduction Gear)

This group contains the actual “العتاد” for the Low range, which is driven by the countershafts and, when selected, drives the FAW J6P مغزل الصندوق الفرعي.

1. عنصر: ‘Low gear – رمح الإخراج’ (1701542-A7G)
هذا (شركات 7) is the ‘Low gear’. This is a large, wide, heavy-duty gear that is in *constant mesh* with the drive gears on the auxiliary countershafts (like the ‘Sub-Box Left Upper Centre Shaft’).

ال Freewheeling Logic أمر بالغ الأهمية. This gear (شركات 7) sits on a large bearing (شركات 9) and *freely spins* on the FAW J6P مغزل الصندوق الفرعي (شركات 5). It is always being spun by the countershafts, but it does not transmit any power *until* the ‘Sliding gear sleeve’ (شركات 3) slides backward and locks onto its dog teeth.

2. ال “Positioning” مجموعة (شركات 6, 8)
This group includes: ‘Limiting washer – معدات منخفضة’ (شركات 6) and ‘Positioning washer – معدات منخفضة’ (شركات 8).

ال Thrust Logic is their function. These two hardened steel washers act as “thrust washers.” They are placed on the front and back faces of the ‘Low gear’ (شركات 7). They create a “sandwich” that controls the gear’s “axial end play” (fore-and-aft movement) on the FAW J6P مغزل الصندوق الفرعي. This ensures the gear stays perfectly aligned with the countershaft gears and the synchronizer sleeve.

جوهر 4: ال “تحمل & Speedometer” منطق

This final group includes the main support bearing for the FAW J6P مغزل الصندوق الفرعي and the components that drive the speedometer.

1. عنصر: ‘Double-row tapered roller bearing’ (350614X4DR-1)
هذا (شركات 9) is the main bearing for the *rear* of the FAW J6P مغزل الصندوق الفرعي. This is an extremely heavy-duty, “double-row” tapered roller bearing.

ال Support Logic is absolute. This one bearing, pressed onto the FAW J6P مغزل الصندوق الفرعي (شركات 5) and into the rear of the gearbox housing, is designed to handle *all* radial loads (from the driveshaft) and *all* axial thrust loads (from the helical gears) in *both directions*. It is the main “anchor” for the entire output shaft.

2. ال “Speedometer” مجموعة (شركات 11, 10)
This group includes: ‘Driven gear – for speedometer drive’ (شركات 11) and ‘Counting tooth washer’ (شركات 10).

ال Speed Sensor Logic is their function. The ‘Driven gear’ (شركات 11) is a small plastic gear (often called a “speedo gear”) that is pressed onto the FAW J6P مغزل الصندوق الفرعي (شركات 5). As the spindle rotates, this gear spins.

This gear (شركات 11) then meshes with a “drive gear” on the electronic speed sensor, which sends the road speed signal to the dashboard. The ‘Counting tooth washer’ (شركات 10) may be a “حلقة لهجة” for an ABS or electronic sensor, or it may be a simple spacer, depending on the truck’s specific model. It is an integral part of the FAW J6P مغزل الصندوق الفرعي‘s data-output system.
